Color Blindness Simulation

Color vision deficiency is a very complex topic, and I could not describe the different causes any better than Wikipedia does, so if you want to learn more, you should check out their article about color blindness.

How-to use Converting Colors

Conversion

To convert, paste a string in one of these color formats, for example, "3CE9A1", into the input field and click on convert. The result will be in the section Conversions, and the following sections will provide you with further details on the color.

Some color formats use the same notation, and the conversion will guess the composition of the search query. As an example, if you try to convert the string "155°, 74%, 91%" it could be an HSV or HSL color, the conversion will assume HSL in this case.

As this could lead to wrong conversions, you can define which format you are passing by wrapping your color string in brackets with the format in front. The search string "HSV(155°, 74%, 91%)" will give you the correct HSV color as there is no need to guess the format. Other examples would be "CIELAB(82.81, -59.41, 22.87)", "CIELCH(83, 63.659, 158.947)", "YXY(61.8117, 0.2619, 0.4325)" and "CMYK(0.74, 0.00, 0.31, 0.09)".

Details

In the details section, you first get a summary of the color and, if available, a description like "dark muted red". You can see the color distribution in different formats. For example, in the RGB format, you get to know the amount of red, green, and blue in your color.

At last, you get brightness and saturation gradients of your color in 10% steps. So if you need a brighter or darker version, you can pick it from here.

Harmonies

The harmonies basically show you colors that go well with the color you are currently viewing. If you like one of the harmonies, you can directly create a 🌈 CSS Gradient or 🔧 CSS Text Shadow from it or view the harmony as a 🖌️ Color Bucket.

SVG Images

This short section shows you a selection of SVG files using the current color. You can download these files and use them in your projects, for example, as a background image.

Previews

You want to see how your color looks on a white or black background? Then you should check out the "Previews" section of the color page.

You also see the color contrast of your color on these backgrounds and get a link to the Color Contrast Checker with your color preselected.

Color Blindness Simulation

When you select a color for your project, you might want to keep in mind how this color is perceived by anyone with a color vision deficiency. Therefore I have added this section showing you previews of your color for different color vision deficiencies.

CSS Examples

If you are new to web development, you might want to see how to apply your color as foreground, background, or border color. The "CSS Examples" section gives you exactly this, help how to use the current color in CSS.

If you are viewing a color in a format not available in CSS, then you will see the color converted to a compatible format.

Color Bucket

You decided on colors for your next project and want to download them as a palette or share them with friends to discuss your decision? Then you should have a look at the color bucket. It allows you to store up to 10 colors, auto-creates color palettes for each of these colors based on the lightness, and gives you a WCAG matrix.

You can download each of the color palettes or the selected colors as a GIMP, Adobe® ASE, or Tailwind CSS palette. Additionally, you can view everything as a 🌈 CSS Gradient, 🔧 CSS Text Shadow, or 📷 Color Palette Image.

To add a color to your color bucket, I put a link "❤️ Add this color to the bucket" in the header section of each page on this website.
